Setting Range
These six parameters are used to define the multi-point V/F curve.
The multi-point V/F curve is set based on the motor's load
characteristic. The relationship between voltages and frequencies
must moot: V1 < V2 < V3, F1 < F2
voltage may cause overheat or even burnt out of the motor and
overcurrent stall or overcurrent protection of the AC drive.
